How to Apply for an IPO Online as a Retail Investor in India

Applying for an IPO online in India takes about ten minutes. You need a Demat account, a PAN, and a bank account linked to UPI, then you place a bid through your broker app or your bank net banking, and the money is blocked, not debited.

That is the whole answer. The Jio Platforms IPO buzz has pushed a lot of first-timers to ask "how do I actually apply?", so here is the exact process, the limits, and the mistakes to avoid, with the official pages to check first.

Key takeaways

• You need a Demat account, a PAN, and a UPI-linked bank account before you can apply.
• Retail investors can apply for up to Rs 2 lakh in a single IPO application.
• Payment uses ASBA: the money is blocked, not debited, until shares are allotted.
• You bid in lots within the price band, or simply at the cut-off price.
• Listing now follows a T+3 timeline, so allotment and refunds move fast.

What you need before you apply for an IPO

You cannot apply for an IPO with just a savings account. A few things have to be in place first.

You need a Demat account to hold the shares, a broker account or bank net banking to place the bid, and a PAN linked to your Demat.

You also need a bank account with UPI, because UPI is the standard payment route for retail IPO bids placed through a broker.

Here is the catch: opening a Demat account is free at most brokers, but verification can take a day or two. So if an issue is already open and you have no Demat account, you have likely missed this one. Set it up before the next buzz, not during it.

One rule worth knowing early: one PAN, one application. Duplicate bids on the same PAN are usually rejected, so do not apply twice hoping for a better chance.

How to apply for an IPO online: step by step

Most retail investors apply through their broker app. The flow is short and paperless.

1. Open the IPO section in your broker app and pick the open issue.
2. Enter your bid: choose the number of lots and a price, or tick cut-off price.
3. Enter your UPI ID as the payment method.
4. Submit the application.
5. Open your UPI app, where a mandate request for the bid amount is waiting.
6. Approve the mandate before the deadline. The money is now blocked in your account.

That is it. You do not pay anything yet. The amount simply sits blocked until allotment day.

Honest aside: the step people forget is number 6. If you do not approve the UPI mandate in time, your application stays incomplete and will not be considered, even with the money sitting in your account.

UPI or bank ASBA: the two ways to pay

There are two payment routes, and both block money rather than debit it. The difference is where you approve the block.

ASBA stands for Application Supported by Blocked Amount. SEBI made ASBA the mandatory basis for IPO applications, which is why your money is never taken upfront.

Here is why that matters to you: if you do not get an allotment, the block is simply released. You were never out of pocket, and the balance keeps earning interest while it stays blocked.

How much can a retail investor apply for?

The retail category has a ceiling. A Retail Individual Investor can apply for up to Rs 2 lakh in one IPO.

You bid in lots, not single shares. The lot size and the price band are fixed in the offer document, so your minimum is one lot and your maximum is the most lots that still fit under Rs 2 lakh.

Worked example with round numbers:

• Say the price band is Rs 300 to Rs 315 and the lot size is 30 shares.
• One lot at the cut-off price = 30 x Rs 315 = Rs 9,450. That is your minimum.
• Maximum retail bid = as many lots as fit under Rs 2 lakh, which is 21 lots here (21 x Rs 9,450 = Rs 1,98,450).

These numbers are only an illustration. The real lot size and band come from the offer document for each IPO.

If you are unsure of the price, choose cut-off price. It simply means you agree to pay the final price the company discovers, so your bid is not rejected on a price technicality.

Read the official filing before you apply

Applying is easy. Deciding whether to apply is the real work, and that starts with the official papers, not a forwarded message.

Using the Jio Platforms IPO as the live example, these are the official pages to check as of July 2026:

• SEBI's Jio Platforms Ltd DRHP page
• Jio Investor Relations
• Jio Financials
• Reliance Industries Investor Relations

Below is the official Jio investor relations page captured on 28 June 2026. Screens, menu labels and filings can change, so use the official link above for the latest version.

The document you actually apply against is the prospectus. If the terms confuse you, read DRHP vs RHP for retail investors first, because the price band and lot size you need to bid only appear in the RHP.

Read like a buyer of risk, not a fan of the brand. The filing carries the business model, risk factors, financials and use of proceeds, which is what your bid is really paying for.

The IPO timeline: from bid to listing

An IPO does not stay open forever. It is usually open for at least 3 working days, and you can apply on any of those days.

Here is the part most people miss: your UPI mandate must be approved before the deadline, which is typically 5 PM on the closing day. Many brokers ask you to approve earlier to be safe.

After the issue closes, allotment is finalised and shares list on a T+3 basis, meaning within 3 working days of the close. SEBI moved the market to this shorter timeline, so refunds and listing happen quickly.

If you get an allotment, the blocked amount for those shares is debited and the shares land in your Demat. If you do not, the block is released and the money is fully usable again.

What happens after you apply: allotment and refund

Once the issue closes, the registrar decides who gets shares. This is where oversubscription matters.

When retail demand is higher than the shares on offer, allotment is done by a computerised lottery, and the aim is to give at least one lot to as many applicants as possible.

Here is the honest part: with a heavily oversubscribed IPO, you can do everything right and still get nothing. That is normal, not a mistake on your side.

If you are not allotted, the block on your money is released, usually within a day or two of allotment. If you are allotted, the exact amount is debited and shares are credited before listing.

Can you edit or cancel an IPO application?

Yes, within limits, and only while the issue is still open.

A retail investor can revise the bid, change the number of lots, or withdraw the application before the issue closes, using the same broker app or bank portal.

Here is the catch: once the issue closes, you cannot cancel. So decide your final lot count before the closing deadline, not after.

Common mistakes when applying for an IPO online

Small slips cause most rejected applications. Watch for these.

• Not keeping enough balance for the full blocked amount.
• Forgetting to approve the UPI mandate before the cut-off.
• Filing multiple applications on one PAN.
• Entering a wrong UPI ID, or one not linked to your PAN-mapped bank account.
• Applying only for a listing pop without checking the business.

That last one is not a technical error, but it costs the most. Listing gains are not guaranteed, and a familiar brand does not remove valuation risk.

Should beginners apply at all?

You can learn about IPOs without applying to every one. Direct company risk is heavier than most beginners expect.

If you are still building comfort, pooled products are a gentler start. PaisaSeed has SIP & Mutual Funds guides for readers who want to understand investing before taking on single-stock risk.

Not sure whether to back a fund manager or a plain index? Read index funds vs active mutual funds for beginners before you decide where your first rupees go.

And if you already run a monthly SIP without knowing what you actually own, SIP is not an investment will help you separate the method from the asset.

Bottom line

Bottom line: applying for an IPO online in India is a short, paperless process once your Demat, PAN and UPI are ready. Bid in lots within the price band, cap yourself at Rs 2 lakh as a retail investor, and approve the ASBA block before the deadline.

The easy part is the application. The important part is reading the filing first and deciding with your own risk limit, not because a name is famous.
